490-1729 6.1 mm ID Intake Valve
Cat® Engine Cylinder Head Intake
Description
Valve Description:
The intake valve is the component that allows air and fuel to enter the combustion chamber during the intake stroke. It is usually made of durable material such as steel and is designed to withstand the high temperature and pressure in the combustion chamber. The valve is located at the top of the engine cylinder head and is typically opened by a camshaft driven by the engine crankshaft.
Features
- By regulating the air-fuel mixture, the engine can run at maximum power with minimum emissions.
- Rockwell hardness scale value of 35 – 45, indicating resistance to deformation.
Applications
The intake valve acts as an inlet, directing air and fuel into the combustion chamber. It is widely used in Cat engine motor graders, engines (piston), tree harvesters, OEM applications, excavators, Base Machine-COSG-336E Hvg, Base Machine-COSG-336E L Uhd, wheel dozers (for scrapers), articulated trucks, trucks (including truck dozers), wheel loaders, track loaders, engine common platform (C13), power systems, engine common platform (C9), generator sets, track-type tractors, drills, material handling, pipelayers, and paving equipment.
